Abstract
The present disclosure relates to apparatus and methods for isolating a tool, such as a sand control screen, from axial and/or torsional loads applied to a tubular string. A sand screen assembly includes a sand control screen, a fixed-end coupling, and a free-end coupling. A first end of the sand control screen is coupled to the fixed-end coupling by a secure connection, and a second end of the sand control screen is coupled to the free-end coupling so the second end of the sand control screen is free to rotate or move axially relative to the free-end coupling.
Claims20
A screen assembly, comprising:
- a sand control screen;
- a fixed-end coupling, wherein a first end of the sand control screen is coupled to the fixed-end coupling by a first secure connection;
- and
- a free-end coupling, wherein a second end of the sand control screen extends through a middle section of the free-end coupling having a smooth inner surface to be movably coupled to the free-end coupling.
A screen assembly, comprising:
- a sand control screen;
- a perforated tubular disposed radially outward the sand control screen;
- a first coupling, wherein a first end of the sand control screen and a first end of the perforated tubular are connected to the first coupling;
- and
- a second coupling, wherein a second end of the sand control screen extends through a middle section of the free-end coupling having a smooth inner surface to be movably coupled to the second coupling, and a second end of the perforated tubular is connected to the second coupling.
A method of deploying a tubular string in a wellbore, comprising:
- coupling a sand screen assembly to a tubular string, wherein the sand screen assembly includes:
- a sand control screen;
- a fixed-end coupling, wherein a first end of the sand control screen is coupled to the fixed-end coupling by a secure connection;
- and
- a free-end coupling, wherein a second end of the sand control screen extends through a middle section of the free-end coupling having a smooth inner surface to be coupled to the free-end coupling so the second end of the sand control screen is free to rotate or move axially relative to the free-end coupling;
- and
- running the tubular string and the sand screen assembly into the wellbore.
